Q: Cohesionless soil is :
  • A. Silt
  • B. Sand
  • C. Clay
  • D. None of the above
Correct Answer: Option B - Cohesionless soil– The soil particle are not sticking to each other or No plasticity. • Exp:– sand, gravel (particle soil range 0.06 mm to 200 mm) • They have no plasticity and lack of cohesion especially when dry. Cohesive soil– Fine grained particle are closely integrate and stick together or having high plasticity. Particle range- 0.06 mm or less
